How are absorption lines produced

Web13 de jan. de 2024 · An absorption line is produced when a photon of just the right energy is absorbed by an atom, kicking an electron to a higher energy orbit. The photon had energy = the difference in energy of the energy orbits. Because the energy levels in an element's atoms are fixed, ... Web9 de jun. de 2024 · $\begingroup$ That diagram makes a lot of sense, however I have some doubts about using this principle for the sun. The thing is that the sun is (approximately) spherically symmetric (around its center), meaning that if you calculate the total power radiated out of a shell with a radius of 1 AU, with the usual absorption lines, and …
